The Fabrication and Characterization of Interpenetrating SiC/Mg Composites

Article Preview

Abstract:

The SiC network ceramics was prepared by the organic foam impregnation method and presureless sintering technologies. The network interpenetrating co-continuous SiC/Mg composites were fabricated by means of pressureless infiltration technique. The results showed that The coarse surface of the SiC network ceramics was observed in the SiC network ceramics, which was benefit for the reaction of the metal alloy during the impregnation process. The continuous and gradual interface can be found in the SiC/Mg composites. It was demonstrated that better interface structure was helpful for improving the bonding strength. Key words: Network Interpenetrating, Interface , Pressureless infiltration
